I'd lean more towards leaving a hypothetical partner out of the whole statement.

Realistically, it's no one's job but her own and definitely something she can handle.

If you want to do it, that's your call, but DO NOT use that middle statement. ever.

Honestly, there's not a lot of ways you can say "No" nicely, so I'd just say something like

"you need to make your own appointments" and leave it at that.

I wouldn't get into a big wordy explanation why. That just seems counter productive.


OR

Just say "NO"

OR

Just don't respond

I like the boundary feeling of my above statement, though.
